Fig. 5 is the view of the alternative embodiment of the present invention according to Fig. 4.
Detailed description of the invention
In the following description, word and the wording of such as bottom surface, bottom etc. is employed.These words should be interpreted as referring to the chain saw be in conventional use and restoration position, all positions as shown in Figure 1.
The chain saw 1 comprised according to handle piece 2 of the present invention has been shown in Fig. 1.Engine foundation 3 comprises engine, and this engine is connected to the chain 4 on bar 5.Handle piece 2 comprises back handle 6, and typically, this back handle and fuel tank 9 form one.Front hand grip 7 is supported on handle piece 2, and handle piece 2 and engine foundation 3 are joined together in mode previously known in this area.The various safety devices of such as kickback guard 8 also can be known from prior art.
Fig. 2 shows the perspective view of the handle piece 2 seen from below.Can be clear that at this, back handle 6 and fuel tank 9 form.Bridge portions 10 extends along direction forward to support front hand grip 7 (it is not shown in detail in this figure).Further, in complete chain saw 1, engine foundation 3 will be placed in bridge portions 10.
Handle piece 2 is by plastic material well known in the prior art, make with two parts by jet moulding.These two parts junction surface (joint) 11 place be joined together by Vibration Welding.Junction surface 11 around handle piece 2 circumferentially.Because Vibration Welding requires that the region at junction surface 11 has a certain specific minimum wall thickness (MINI W.), and the wall thickness of handle piece 2 is less than the wall thickness required by welding usually, therefore junction surface 11 protrudes beyond surface 13 certain distance of surrounding, and surface 13 at least is around that in the region of plane, (such as at the bottom surface place of bridge portions 10) is like this.
Junction surface 11 has and contributes to the ad hoc structure that it protrudes beyond the surface 13 around it.In vibration welding process, weld seam 18 will be formed between two surfaces contacting just.Unnecessary material may flow to the side of weld seam.In order to maintain one and clean and tidy appearance, two guard members 19,20 extend and exceed this weld seam on weld seam 18, to form the open space being used for any excess stock between this two guard members and weld seam 18.In a word, there is the surface 13 that the junction surface of its weld seam 18 and guard member 19,20 protrude beyond surrounding.
On the either side at junction surface 11, fin 12 is arranged on the bottom place of handle piece 2.This is also clearly from Fig. 3.Each rib 12 protrudes certain distance from the adjacent bottom wall 13 of handle piece 2.Rib 12 (having two in the preferred embodiment) at least protrudes into degree the same as junction surface 11.Therefore, diapire 13 is depressions relative to the at utmost projection of junction surface 11 and rib 12.
In the preferred embodiment, rib 12 is preferably arranged on the both sides at junction surface 11.But, according to width and the position thereon, junction surface 11 of bridge portions 10, incomplete same from a corresponding rib 12 to the distance at junction surface 11.The position of junction surface in bridge portions 10 and just all in all in handle piece 2 depends primarily on the consideration in manufacture.
Rib 12 is whole or be at least partially disposed under closed volume or multiple volume.Therefore, rib not only can be arranged on the outside of fuel tank 9, but also can be arranged on the bottom surface of back handle.In most cases, have inwall between back handle 6 and fuel tank 9, and also have inwall in bridge portions 10, the part of bridge portions separates with fuel tank by this inwall.
In order to obtain maximum beneficial effect from rib 12, these ribs, preferably as far as possible away from being arranged in bridge portions 10, to give rib maximum torsion resistance, and protect whole bottom surface be not scraped off or wear and tear.These ribs also increase the bending resistance of bridge portions 10.
Although have nothing to do from the bearing of trend arranging the beneficial effect that obtains of the rib 12 and rib 12 at least protruding into degree the same as junction surface 11, these ribs are arranged along the longitudinal direction of bridge portions 10 in the preferred embodiment.The reason done like this has two.First, make manufacture handle piece 2 two parts will as far as possible simply.Secondly, when junction surface 11 and rib 12 extend along equidirectional, the bottom surface of handle piece 2 will not have little depression and enclosure (enclosure), these grooves and enclosure may assemble dust, or the irregularity in twig or tree surface may be tangled when these grooves and enclosure.
When being put in the plane by chain saw 1, arranging two ribs each other abreast and also greatly contributing to the stability of chain saw, and preventing chain saw from falling to side, because this increasing texture, this texture may be very important for the possible buyer of chain saw.
The cross-sectional view intercepted along the line A-A in Fig. 3 in reference Fig. 4, this figure will provide more about the shape of rib 12 and the information of position.And clearly show the material thickness in the region at junction surface 11 in the figure.Rib 12 protrudes at least identical with junction surface 11 degree at the bottom surface place of bridge portions 10 from surface 13.Therefore, substantially maintain the outside height of bridge portions 10, therefore need not redesign other parts of chain saw 1.
Equally, when not increasing the overall outer dimensions of bridge portions 10, allow rib 12 to be arranged to the distance at a distance of same with the width of bridge portions 10.This causes rib 12 to be arranged near each sidewall 14 of bridge portions 10, and can not extend to significantly outside sidewall 14.
Due to when chain saw 1 pushed over logs or branch, rib can be exposed in main wearing part, therefore, for make rib 12 as far as possible durable, rib 12 preferably should have wide supporting surface 15.Meanwhile, just all in all, the material thickness of handle 2 preferably should as far as possible homogeneous.For meeting this two requirements, in the preferred embodiment, rib 12 has the shape of cross section shown in Fig. 4.Supporting surface 15 extends along this diapire in distance diapire 13 a distance, and forms the bottom of each rib 12, and top (that is, vertical wall 16) extends between diapire 13 and each supporting surface 15, thus forms the rib 12 with hook-like cross-section.Preferably, diapire 13, sidewall 14, supporting surface 15 and vertical arm 16 all have identical material thickness.The supporting surface 15 of each rib 12 is wider than material thickness, and this makes rib more durable.Each rib fitted lining (line) can also have harder material, such as stainless steel.This can produce T-shaped as shown in Figure 5.Such rib has good anti scuffing and the ability of wearing and tearing certainly.
Internal rib 17 extends from each sidewall 14, to increase the rigidity of bridge portions 10.
Certainly, the shape of rib 12 can change, and its position also can change equally.Fig. 5 shows alternative embodiment, and wherein, the shape of cross section of rib 12 is different from the shape of cross section of this preferred embodiment.Something that emphasis will be considered when selecting the shape of rib 12 be keep material thickness as far as possible homogeneous.Secondly, the simplification of manufacture is also by the selection of impact to the shape of suitable rib.The shape needing so not complicated shaping jig will be preferred.
If needed, rib 12 can with distance each other and the less distance in distance junction surface 11 arrange.The length of rib can change, and can have one or more interruption, that is, have a series of multiple shorter rib 12 in alignment, instead of the rib 12 that long.
Although embodiment substantially parallel for rib 12 is described as preferred embodiment above, the application that rib 12 and junction surface 11 are arranged angularly is also useful.
Under the prerequisite of scope not deviating from claims, can further amendment be made to the present invention and change.
